If after installing Linux Mint in EFI mode, your computer skips the boot menu and boots straight into Windows (or another operating system), you probably have an issue with the boot order.

To modify the boot order:

Boot Linux Mint in live mode (with your USB stick or DVD).

Open a terminal.

Type sudoefibootmgr.

This command lists the available boot options and the boot order.

In the screenshot above, there are three boot options:

ubuntu at 0000

linuxmint at 0001

MacOSX at 0081

The boot order is 0081. This indicates that the computer only tries to boot Mac OS and not Linux Mint.

Important

For technical reasons Linux Mint uses ubuntu as its EFI boot name.

To fix the boot order, type sudoefibootmgr--bootorderXXXX,YYYY (where XXXX and YYYY are the operating system boot options you want to boot).

In the screenshot above, sudoefibootmgr--bootorder0000,0081 instructs the computer to first try to boot Linux Mint (ubuntu being the EFI boot name for Linux Mint), and then Mac OS.

Restart the computer.

Note

In the screenshot above 0000 is the first boot option so the computer boots on the Linux Mint grub menu. If grub fails (or if it is dismissed with the exit command), the computer follows the boot order and then tries to boot 0081, which corresponds to Mac OS.
